The Premier League's Top Defenders: Van Dijk Leads New Grading System
While opinions on the best defenders often rely on reputation or highlight moments, a new analytical system offers a data-driven look at performance. Gradient's Player Grades, which measure execution on thousands of in-game events, have ranked the top ten centre-backs in the Premier League this season. The results confirm some established stars while also highlighting several underrated performers.
How Player Grades Are Calculated
The ranking is based on Gradient's proprietary grading system, which focuses on execution rather than simple outcomes like goals or tackles won. Analysts evaluate over 2,000 events per match, covering every action a player makes from aerial duels to dribbles and passes. Each event is graded on a scale from -2 to +2, where zero represents expected execution, and positive or negative scores indicate better or worse performance than anticipated. These grades are then aggregated into an overall 0-100 performance score across more than 50 categories, providing a comprehensive season rating.
This method aims to cut through noise and bias, offering a clearer picture of who is consistently performing their defensive duties effectively, regardless of their team's overall results or public perception.
The Top 10 Centre-Backs of the Season
Here is the list of the highest-rated defenders according to Gradient's data for the current campaign:
- Virgil van Dijk (Liverpool) – 81.9 – Despite criticism, the Liverpool captain remains the highest-graded defender, leading in total events and aerial duel success rate (74%).
- Ezri Konsa (Aston Villa) – 75.9 – Excels in positioning events above expectation and boasts the highest tackle success rate among centre-backs.
- Jan Paul van Hecke (Brighton) – 75.7 – A second consecutive top-ten finish, though his score has dipped from last season's 82.0.
- Gabriel Magalhaes (Arsenal) – 75.5 – Rated higher than his partner William Saliba this term, who sits outside the top ten.
- Lisandro Martinez (Manchester United) – 74.6 – A clear asset when fit, though his grading doesn't capture certain stylistic quirks.
- Malick Thiaw (Newcastle United) – 74.4 – Considered Newcastle's standout summer signing, performing excellently in his first Premier League season.
- Marc Guehi (Manchester City) – 73.9 – Leads in interceptions performed above expectation, a bargain acquisition for City.
- Ruben Dias (Manchester City) – 73.3 – Still a key figure despite new competition, forming a promising partnership with Guehi.
- Lewis Dunk (Brighton) – 73.2 – No defender has applied more pressures on shots, embodying a classic, physical style.
- Marcos Senesi (Bournemouth) – 73 – Leads the league in total clearances and interceptions, a vital presence for his team.
Key Takeaways from the Data
- Van Dijk's Dominance: Even in a perceived down year for Liverpool, Virgil van Dijk's individual execution metrics place him clearly at the top, particularly in aerial dominance and overall involvement.
- The Brighton Pair: Brighton's defensive strength is highlighted by having two centre-backs (Dunk and van Hecke) in the top ten, a feat matched only by Manchester City.
- Underrated Performers: Players like Ezri Konsa, Marcos Senesi, and Malick Thiaw receive data-backed validation for their often less-heralded but highly effective contributions.
- Partnership Dynamics: The ranking shows that having a high-rated partner (like Gabriel with Saliba, or Dias with Guehi) doesn't guarantee both individuals will score highly, as performance is graded individually.
- Value Identification: The system suggests some transfers, like City's move for Marc Guehi, were exceptionally good value based on the player's immediate high-level execution.
While no grading system is perfect, this data-driven approach provides an interesting counterpoint to conventional narratives about defender quality. It emphasizes consistent, above-expectation execution in all facets of play, rewarding players who may not always be in the spotlight.
